Legal claims defining the scope of protection, as filed with the USPTO.
2. The computer program product of claim 1, wherein μ is a preset constant.
3. The computer program product of claim 1, wherein μ is a value based on the LPC parameter and the synthesized high-band signal.
5. The computer program product of claim 4, wherein β=0.5, and wherein γ=0.8.
8. The computer program product of claim 7, wherein μ is a preset constant.
9. The computer program product of claim 7, wherein μ is a value based on the LPC parameter and the synthesized high-band signal.
11. The computer program product of claim 10, wherein β=0.5, and wherein γ=0.8.
12. The computer program product of claim 7, wherein the low frequency encoding parameter comprises an algebraic codebook, an algebraic codebook gain, an adaptive codebook, an adaptive codebook gain, or a pitch period.
13. The computer program product of claim 7, wherein the speech signal is in a time domain or a frequency domain.
16. The method of claim 15, wherein μ is a preset constant.
17. The method of claim 15, wherein μ is a value obtained based on the LPC parameter and the synthesized high-band signal.
19. The method of claim 18, wherein β=0.5, and wherein γ=0.8.
20. The method of claim 15, further comprising obtaining an excitation signal according to the low frequency encoding parameter, wherein obtaining the synthesized high-band signal, comprises obtaining, according to the excitation signal and the LPC parameter, the synthesized high-band signal.
